Infleqtion focuses on quantum technology by developing smaller, portable quantum-enabled products that can be used in various industries. Their offerings include quantum sensors and devices like Atomic Prisms and ion devices, which ensure data integrity from the edge to the computer. Unlike many competitors that aim to build large quantum computers, Infleqtion's approach emphasizes software-configured solutions that are accessible to a broader audience. They also provide a quantum software platform called Superstaq, which allows users to create quantum programs in any programming language and achieve significant performance improvements. Infleqtion's goal is to accelerate the commercialization of quantum technologies through partnerships, such as their collaboration with the Department of Energy, while generating revenue from their diverse range of quantum products and software solutions.
